The Grimm Audio TPR8 Multicable is a reference-grade eight-channel bulk cable for professional audio facilities that require clean, space-efficient and precisely configurable signal distribution. Sold by the metre and without connectors, TPR8 is the ideal foundation for custom DB25 breakouts, XLR fanouts, patchbay looms, converter wiring and eight-channel analogue or AES/EBU cable assemblies.
 
Designed for demanding broadcast studios, mastering rooms, mixing environments and recording facilities, TPR8 combines eight individually shielded TPR channels within one robust outer jacket. It was developed specifically as a premium multicore solution for AD/DA converters, monitor controllers, mixing consoles and other multi-channel professional audio hardware. Instead of compromising performance for density, Grimm retains the core TPR design principles: symmetrical conductor geometry, heavy shielding and a conductive interface layer that helps minimise microphonics and improve RF immunity.
 
With a 110 Ω characteristic impedance, TPR8 is technically suitable for AES/EBU applications as well as balanced analogue microphone and line-level connections. The cable is particularly effective where multiple channels must be routed over a common path: converter-to-console connections, mastering insert chains, broadcast routing, multi-channel monitor systems and custom stage or FOH looms. At 13 mm in diameter with a 100 mm minimum bend radius, it provides an efficient alternative to running eight individual cables while maintaining a professional-grade signal path.
 
For professional live applications, TPR8 offers a practical way to create reliable multi-channel snakes and breakout systems for stage racks, monitor control, playback rigs and broadcast splits. For permanent installations in public venues, theatres or regulated commercial spaces, installers should always confirm compliance with all applicable local fire-safety, building and installation requirements.
